' CLOSURE FOR RECEEPTACLES.

Toall whom it may concern: I

Be it known that I, FERNAND LALAU, residing at Paris, France, have invented a new and useful Improvement in Closures for Receptacles, which improvement is fully set forth in the following s ecification.

This invention has f br its object an arrangement for closing any type of receptacle having a sufliciently rigid mouth.

The arrangement consists of two main parts: 1. A cap or capsule, the crown of which may be entire or cut away, and whose sides have in them several longitudinal slits and are turned or rolled inwards for a certain length. 2. A continuous ring or band, or one having its ends separably connected by hook and eye, of such a size that it can be made to fit tightly upon the capsule. A disk shaped or annular washer of cork, india rubber or other suitable material, is used in addition to these two essential parts, to insure that the closing shall be hermetical and firm. Before application, the arrangement assumes the form of a capsule whose sides are artly cylindrical, and for the rest of their ength flaring out and split, and whose ed es are turned or rolled inwards. The ca su e contalnsthe washer, and onits cylin rical part the r ng is fitted.

The arrangement is applied by placing the assemblages of elements on the mouth of the receptacle. Pressureis exerted on the capsule in such a way as to crush the washer against the rim of the receptacle, then the ring is forced down over the sides of the capsule which are thus bent inwards and confined in engagement with the receptacle or under a flange on it.

The receptacle is opened by removing the This is facilitated b'y'en'iploying a separing fastened by a hookand eye. The ca sule is then easily removed. V

he cap with part of its crown cut away is used when it is not necessary to completely cover the lid of the receptacle. In the case where the rece tacle has .an independent cover to be 'hel in place by this method of closing, the wa'sherelastic or not-is placed between the cover and the receptacle.

The drawings annexed show examples of some ways of carrying out the lnvention.

In the drawings Figure 1 shows the diiferent Eiirts before they are assembled according to t -Specification of Letters latent.

in section through one of the slits an larger scale the parts in osition on the receptacle. Figs. 3 and 4 s ow modifications. Fig. 5 shows in section the arrangement applied to closing a bottle with a grooved head. Fig. 6 is a similar section of a bottle having an angular head. Fig. 7 is a similar section illustrating the application of the invention to a receptacle with an independent cover which is completely covered by the capsule. Fig. 8 shows an example in which the independent cover is not com letely covered by the capsule. ,Figs. 9 an 10 are variations showing different forms .of slits in the capsule. Fig. 11 shows a closure a plied to a cylindrical vessel with smooth si es.

In Figs. 1 to 4 the receptacle 1f to be closed is flaring with smooth sides. Fig. 1 shows the different elements separately and ready vto be assembled before use. These elements consist of: 1st. The elastic washer 2 of sufficient diameter to cover the edges of the receptaclerfflnd. The capsule 3 whose internal diameter is the same as that of the washer 2, and whose side walls are cylindrical in their up er part and flare out in their lower part and aving in them longitudinal slits 4, the sides being bent or rolled inwards at 5 for a suitable portion of their 'length. 3rd. The band 6 having its ends separably connected by a hook and eye at 7 or continuous. This band is Of such diameter that when pressed home onto the capsule 3 it forces 1ts sides inwards, so that they become cylindrical instead of conical.

Fig. 2 shows the various parts in position.

A tight joint is insured at 8 by the elastic washer 2. The turned in edges 5 ofthe capsule 3 are firmly pressed against the receptacle 1 by the ring 6 and cannot rise owing to the conical shape of the receptacle 1. An effort to pull upwards tends to unroll and jam the turned in edges against the glass.

The walls of the capsule can be made of different forms, either smooth as in Figs. 1, 2 and 4, or grooved as shown at 6 in Fig. 3 to give them more elasticity at the points of contact with the receptacle, or again may be of any other form suitable for this invention. They m. y in particular have in them teeth 6 directed dowmwards which firmly en age with similar and oppositely directed teet 7 'in the-ring to insure that the receptacle shall In the case of receptacles whose edges are' not smooth that is to say having one or more moldings of any form either raised or sunk,

the turned in edges 5 engage firmly with one or more of these'moldings. Their form and size is of course adapted to the receptacle to be closed.

Figs. 5 and 6 show the closing of bottles or jars of this sort in which the neck has a grooved head 10 or a shar an led head 11.

If the receptacle has a id of its own the present system of closing is also a plicable so that the lid is completely covere up or is left visible. In the first case as shown in Fig. 7 the elastic washer is placed under the lid of the receptacle; it is either .a com lete cover or an annulus according to the s ape.

of the lid. The closing is otherwise the same as in the preceding cases. In the second case, the washer is arranged in the same way 'as just described but the capsule is cut away in the middle as is shown m Fig. 8. It is reduced so as to be only an annulus which it is advantageous-to cut into sections to facilitate opening the receptacle.

The shape, number and size of the slits in the ca sule are arranged according to the nature o the material employed for the different pieces. Figs. 1 to- 8 show simple slits, 9 and 10 show modifications but other convenient forms may be used; Similarly the le th of the slits depends on the dimensions o the sides of the capsule.

The opening of a receptacle closed by means of a complete ring 6 may be performedfor exam le by forcing ofl' thisring by means of a sultable tool but when the re ceptacles have to be opened by hand the ends of the ring 6 are preferably connected by a hook and eye 7, undoing which frees the capsule which can then be easily taken off.

As will be readily seen the present invention can be easily applied to closing all kinds of receptacles among others cylindrical receptacles where there is no internal pressure or when it is slight. It may then be advantageous in certain cases to prevent displacement by sliding to interpose a suitable elastic or slightly plastic ring between the recep tacle and the turned in edges of the sides *of the capsule.

Having thus described my invention what I claim as new and desire to secure by Letters-Patent, is:- 4 j 1. The combination, witha receptacle, of
